I am developing a BPMN process in Activiti. Whenever I add a signal definition to my process or leave the "collaboration" tag inside the XML file, I am getting a "Error Parsing XML" message.
<collaboration id="Collaboration"> <participant id="klausurstellung" name="Klausurstellung" processRef="klausurstellung"></participant> </collaboration> <!– process –> <!– the signal is further defined within the process –> </blockcode>
If I delete both, the collaboration tag and the signal definition inside of my BPMN diagram. The process deployment works.
This is the error stack trace:

I have checked the forum and added the cxf dependencies to my Tomcat/lib folder.
